高升油田强穿透活性解堵技术

高升油田难采储量区块和注水区块开发过程中,由于油藏埋藏深、储层物性差、粘土含量高、储层受伤害等原因,注汽和注水困难,蒸汽吞吐和水驱油效果差。针对高升油田长期以来存在的主要问题,进行了强穿透活性解堵技术的研究。应用表明强穿透活性解堵剂可有效解除油层污染,提高近井地带储层渗透率,降低注汽和注水压力,增加注汽和注水量,提高区块开发效果。

Strong penetrated active plugging removal technology in Gaosheng oilfield

In the development process of hard recoverable reserves and injection blocks in Gaosheng oilfield, gas and water injection is difficult, steam stimulation and water flooding effect is bad due to deeply buried reservoirs, poor reservoir properties, high clay content, reservoir damage and other factors. The strong penetrated active plugging removal technology has been studied aiming at main problems existed in Gaosheng oilfield for a long time. The application shows that the strong penetrated active plugging removal can effectively release the oil pollution and increase the near wellbore reservoir permeability, decrease steam injection pressure and increase the quantity of gas and water injection, which improve development effect of the block.
